Study of faint stars using multicolor CCD data: tidal debris in the
Sextans dwarf spheroidal galaxy; limits on galactic or local group baryonic
dark matter; metallicity of stars in the M31 outer spheroid.

Search for Kuiper-belt comets; series of short CCD exposure of low
ecliptic latitude fields are filtered in order to identify objects with apparent
speeds of a few arcsed/hour.

Gravitational lensing by galaxy clusters: systematic distortion of the
shapes of background faint blue galaxies; estimates of the mass distribution
in rich clusters at z=0.2-0.5.

Interacting galaxies: gas content and distribution; kinematics, stellar
populations, and star formation in the merger remnant NGC 7252 (the
"Atoms-for-Peace" galaxy) and in the group of galaxies surrounding the
shell galaxy NGC 5018.

Dwarf galaxies: an H I survey of the Perseus-Pisces super-cluster and
a foreground void; properties of 21-cm selected dwarf galaxies.
